GE 6SN7GTB 6SN7 ECC33 Tubes, Matched Pair, NOS, NIB, Tested [Expired]

Hello – I have a matched pair of GE 6SN7GTB ECC33 tubes for sale.
These tubes are NOS and new in the box.
These tubes have gray ladder plates with side mount double bar “D” getters. Date codes are from 1959 and 1963.
TV-7/B test results: 98/95 and 100/100. Minimum is 50.
They have also been checked for noise and microphonics in the phono stage of my DIY pre-amp and are dead quiet.
All tubes are tested on my calibrated TV-7/B or on my calibrated Hickok 539C. All of these tubes have been tested for transconductance, shorts, gas, leakage and life. All tubes meet or exceed manufacturer published specifications of transconductance (Gm) for the specified tube type. All tests are tested twice – prior to the listing and prior to shipping.
